Hi,

Since you mentioned that you are waitlisted, it is better to wait for the final results or further updates. Along with that you can apply to other universities for the same. Applying for the same thing again can get your application rejected due to double application. Also, GRE score is just for admission in Universities or colleges outside India. It is advisable to wait for the next update and stick to the qualifications that are required. Adding excess and irrelevant details in any application is not always beneficial.

I hope this helped you.

All the Best!
